Temperatures reached 22C in St James’s Park, smashing March 23’s previous high by 1.2C and making Britain hotter than the Costa Del Sol.But staycationers were still urged to consider their behaviour as the water on our coasts won’t be as warm.The RNLI said the sea is not warm enough to spend much time in, with sea temperatures of 8-10C still among the coldest of the year, amid fears of “cold water shock” deaths.The RNLI said: “The sudden cooling of the skin by cold water causes an involuntary gasp for breath."It only takes half a pint of seawater to enter the lungs for a fully-grown man to start drowning.

You could die. "Anything below 15C is cold water and can seriously affect your breathing and movement, so the risk is significant.”Around 400 people drown in the UK every year.Met Office forecaster Marco Petagna said: “Sea temperatures were at their annual minimum just weeks ago.”Beachgoers were also warned to take jumpers.Friday's temperatures of 23C (73F) made it the hottest day of the year so far and hotter than the Costa del Sol.But coasts will up to 4C chillier from Saturday with cold breezes and even mist.A Met Office forecaster added: “Temperatures are the warmest this year, but might not feel like it by the coast.

Low sea temperatures mean on-shore breezes feel noticeably cooler compared to inland.” To stay up to date with all the latest news, make sure you sign up to one of our newsletters here .Until Sunday, Britain is hotter than 19C Costa del Sol around Malaga, Spain.
